mantaSave.ws: Save current R workspace and uploads to a Manta R workspace...

In joyent/mantaRSDK: Joyent Manta Storage Service R Software Development Kit

Description

Uploads Manta "current.Rdata" object to an audit-trail workspace directory using mantaSave.image.

Usage

mantaSave.ws()

Details

Together with mantaLoad.ws this function works with an audit trail of workspaces maintined in a Manta subdirectory created by mantaSave.ws made by R version and mantaRSDK client hostname, that looks like these:
~~/stor/R-3.0.1/cwvh-macbookpro/
~~/stor/R-3.0.2/CHOGUE-HPDV7/
These workspace archive subdirectories are made by mantaSave.ws when first run.
The last saved R workspace from these two systems in each directory is named "current.Rdata". Previously saved R workspaces are renamed to their original GMT creation date/time stamp on Manta and archived with SnapLinks before writing a new workspace.
Archived workspaces are named like this:
"2014-01-07_14:53:05_GMT.Rdata" To retrieve an older workspace or a workspace saved from a different mantaRSDK client and version, use this form:
mantaLoad("~~/stor/R-3.0.0/hostname/2014-01-07_14:53:05_GMT.Rdata" If you wish to save your workspace to a different location use mantaSave.image Adds appropriate content-type HTTP header, which is set to "application/x-r-data".

Value

TRUE or FALSE depending on success of download.
